Universal control not working iPadOS 16.4/ Ventura 13.3

I may or may not have found a workaround.

1. Turn off hand-off for all affected devices.
2. Restart all affected devices.
3. Turn on hand-off again.

This may or may not work. Worked once for me, at least.

Also, I must stress that this is a potential workaround and not a solution. Restarting devices is a pain anyway.

Universal Control is dead.

I have three Apple devices on my desk - a MacBook Pro, a MacBook Air, and an iPad. All have everything necessary turned on, same local network, strong WiFi connection, etc. In short, everything necessary to make Universal Control work is there. Has always been there for the whole duration of this year and worked every.single.day.

I was able to seamlessly send my cursor across all of them.

After the latest upgrade Ventura, I can not anymore.

Tried everything listed below - both individually and in combination.

1. Logging off and on
2. Logging out from the iCloud account and logging in
3. restarting every device
4. turning off hands-off and then on

I was able to make universal control appear exactly once across MacBook Pro and iPad, and exactly once across MacBook Air and MacBook Pro, but after sending the devices to sleep - it stopped and did not appear again.

I also checked the network settings. Remote desktop using vnc://local IP works so does display --> extend display/mirror display in other devices.

All of these means just one thing: Universal Control is buggy and dead. It is not an issue of the network, or connectivity, or Bluetooth.

Please fix.

So after trying everything (safe mode, removing bluetooth devices, rebooting a million times, etc). My keyboard and mouse on my Mac Studio still couldn't control the MacBook Pro right next to it. This had been working since Universal Control first rolled out in the public betas. Although I would have issues from time to time with laggy mouse or keys repeating, it never just died like it did this morning. Here is what I did:

• Turned off handoff on iPhone, iPad and reset network setting in General Menu (rebooting)
• Turned off handoff on Mac Studio and MacBook and shut down.
• After iPhone and iPad came back online, turned both Macs back on
• Turned on handoff on Mac Studio and MacBook (kept it off on iPhone/iPad as I never use it anyways)
• After about 5 seconds Universal Control started working again.

Apple really needs to work on these weird bugs. For years the USB sleep function was broken on Macs causing external drives to be ejected improperly. They seemed to just recently fix that. So disappointed. A company I have relied on because "it just works" I'm finding more and more often I have to troubleshoot edge cases.

Same issue here, tried updating both to the latest OS version (Ventura 13.3 (22E252)), turning off/on bluetooth & wifi, rebooting, but nothing worked.

I have two macbooks and an iPhone, "copy(mac)/paste(iPhone)" wasn't working either.

Thanks to (https://forums.macrumors.com/threads/13-3-continuity-totally-broken.2385350/) fixed doing the workaround signing-off/signing-in again on both macbooks.

Once I signed-off from the first macbook I tried "copy(mac)/paste(iPhone)" and viceversa, and worked, so I went to do the same in my second macbook.

It seems it began with an update, it going to be annoying if this workaround is required to do for next OS updates...

I have the same problem. My iPhone and iPad still work fine using Handoff but my Mac seems to be the issue. I signed out of iCloud and back in on my Mac. That worked yesterday but this morning it's broken again.

iOS 16.4 and Ventura 13.3 has killed my universal control for my iMac 27” and my iPad Pro which were both working seamlessly before up dating. Also my iMac now cannot unlock with Apple Watch 6. The iMac cannot connect (sync) with my watch. Thank you Apple. How can we fix this?

Been having this problem all week. Just drops out randomly between two M1 Macs (one mini, one MacBook). Usually have to reboot one of the machines to get a chance of it working again. Highly annoying.

Working on & off here, when the screens turn off after a period of no use, the iPad screen isn't showing macOS but it is still connected in the Control Center.

A simple MacBook reboot fixes the issue every time though...

I stumbled upon this Handoff issue with iOS/iPadOS 16.4 after I found that Universal Clipboard is working only iPhone-to-Mac and iPad-to-Mac, but NOT Mac-to-iPad, Mac-to-iPhone or iPad-to/fro-iPhone. Needs an immediate fix.

mine broke after upgrading to 13.3 on my M2 14 MBP. it was working with 13.2, and ipad air 5th, 16.4. done all the standard things, to no avail. i think we deserve a quick fix, these are not in beta :(

For me, I've noticed Universal Clipboard has stopped working. Idk if that's part of Handoff.

EDIT: Idk what happened but Handoff, Universal Clipboard, and Universal Control just started working again. I toggled Sidecar on and off.

To me sometimes Handoff and Universal Control work well and sometimes it stops and even restarting both mac, iPhone and iPad doesn’t work. But sometimes just turning mac wi-fi off and on again it works. I’m not having the problem between iPhone and iPad just from them to Mac. Another problem that even Apple support couldn’t give me the answer (If is normal or a bug) is that when Universal Control is working and I set the iPad sounds to AirPlay in Mac the Universal Control stops immediately. I don’t know if it isn’t possible to use both Universal Control and AirPlay.

Agreed - again and again Apple are dropping the ball on bug fixes and quality control. I have been a full-on iPhone / Mac / iPad / HomePod / Apple Watch consumer for many years, but I can see the company's software products' quality control slipping all the time. It's a downward trend.
